The difference and molding process between liquid silicone and solid silicone

The difference and molding process between liquid silicone and solid silicone

1. What is the difference between liquid silica gel and solid silica gel?

1. Liquid silica gel is relative to solid high-temperature vulcanized silica gel. It is a liquid rubber with good fluidity, fast vulcanization, safer and more environmentally friendly, and can safely meet food-grade requirements.

2. Solid silicone

Solid silica gel is a saturated polymer elastic material, which has the characteristics of high temperature resistance, cold resistance, solvent resistance, edge resistance, anti-sticking, electrical insulation, and chemical resistance. It has a wide range of applications.

Second, the comparison of liquid silica gel and solid silica gel

1. Appearance

a, hence the name suggests, liquid silica gel is in a liquid state and has fluidity,

b. Solid silica gel is solid and has no fluidity

2. Security

a, Liquid silica gel is a highly transparent and safe food-grade material without adding auxiliary materials such as vulcanizing agent when molding, and it is sealed and fed for molding.

b. Solid silica gel is a transparent and environmentally friendly material. It needs time for vulcanization and molding when molding.

3. Molding method

a. Liquid silicone is injection molding liquid silicone rubber (LSR), the full name is injection molding liquid silicone rubber, injection molding machine for vulcanization equipment.

The injection molding machine has a very simple process (no need for manual processes such as ingredients, mixing, cutting, and placing of high-temperature rubber technology, only one worker can take the product, and the product has high accuracy (all manual procedures before molding are all Replacement by machine) High output (A/B glue is mixed at a fixed temperature for a few seconds to form), with many advantages such as labor saving, power saving, and material saving. It can produce all high-temperature glue products.

b. Solid silicone molding is a solid piece of raw material. After being mixed by a mixer, the cutting machine cuts the product and the mold into the appropriate size and thickness and then puts it into the mold. The pressure molding machine does not need to be warm-molded, and when demolding Plastic products are similar, and molds need to be cleaned.
